如何使用ffmpeg通过http协议流 [英] How to stream with ffmpeg via http protocol
问题描述
我正在做一个应该在Flowplayer中正确显示的流。
首先，我通过RTP将其发送到另一台电脑。在这里，我还检查了VLC，编解码器是否正确到达，他们这样做。
I'm currently doing a stream that is supposed to display correctly within Flowplayer. First I send it to another PC via RTP. Here, I also checked with VLC that the codec etc. arrive correctly, which they do.
现在我想将此流作为文件公开到Flowplayer，因此可以通过VLC中使用的东西显示：
http：// localhost：8080 / test.mp4
。
Now I want to expose this stream to Flowplayer as a file, so it can be displayed, via something I used in VLC:
http://localhost:8080/test.mp4
for example.
我得到的全部是： ffmpeg -i输入-f mp4 http：// localhost：8080 / test.mp4
然而，无论我怎么样尝试这样做，我只得到一个输入/输出错误。这是唯一可能的东西像ffserver或另一个？
However, no matter how I try to do this, I only get an input/output error. Is this only possible with something like ffserver or another?
我认为这不行，因为ffmpeg不能作为服务器;在VLC上它可以工作。 （尽管VLC遗弃了我设置的编解码器，但由于某种原因而无法读取）
What I think is this doesn't work because ffmpeg can't act as a server; on VLC it works since it can. (Though VLC ruins the codecs I set and it can't be read afterwards for some reason)
可以使用的（一种）解决方法是将RTP流保存到一个文件，然后让flowplayer加载它。但是，只有在文件不被访问的情况下才有效;
A (sort of) workaround I can use is saving the RTP stream to a file, and then letting flowplayer load it. This, however, only works once the file is not accessed anymore; I get a codec error otherwise.
推荐答案
你需要这个命令行
ffmpeg -f v4l2 -s 320x240 -r 25 -i /dev/video0 -f alsa -ac 1 -i hw:0 http://localhost:8090/feed1.ffm
确保您的Feed名称以.ffm结尾，如果不是这样，请添加 -f ffm之前，手动指定输出格式（因为ffmpeg将无法自动计算出来），像这样-f ffm http：// localhost：8090 / blah.bleh 。
make sure that your feed name ends with ".ffm" and if it's not the case, then add "-f ffm" before your feed URL, to manually specify the output format (because ffmpeg won't be able to figure it out automatically any more), like this "-f ffm http://localhost:8090/blah.bleh".
